On every boot, there is a kernel WARNING related to Xorg. The WARNING line is:
[ 142.852681] WARNING: CPU: 0 PID: 1584 at mm/filemap.c:221 unaccount_page_cache_page+0x12b/0x180
This warning is always related to the Xorg process. I don't know if this WARNING is harmful, but it happens on every boot.
As the system is Xubuntu 18.04, Xorg version being used is 1.19.6. Kernel is drm-tip and Mesa is git.
Processor: Intel Core i3-6100U;
Video: Intel HD Graphics 520;
Mesa: 19.3.0-devel (git-c7e5d24d8f);
Kernel version: drm-tip (09d5abe47441d387053bae89e4f0f832d2c6db2d);
Distribution: Xubuntu 18.04.3 amd64.
